Stoner/Doom Bassists Thread, Part 90: Maxed Out

@Robot.G got the goods for diodes. Silicon is much more prevalent nowadays because of its elemental properties that are favorable for electronics. I'm not that knowledgeable on electronics, but from a Chemists perspective, Silicon is much more stable than Germanium. You can put a Germanium based pedal in the freezer or hit it with hot air from a blow dryer and hear a difference in how it clips. LED, Mosfet, JFET, etc. are also more stable than Ge, so are opamps.

To my understanding, essentially all diodes will clip (cut off or flatten the peaks and troughs) some of the signal passing through them. Think of your impulse signal from the strings and pickup (an electrical transducer i.e. gives out electrical impulses based on the characteristics of the disturbence of its magnetic field [how the string vibrates] surrounding the pickup) as a sine wave. In reality it's a very complicated multioverlaping (harmonics) sine wave. That sine wave passes through those diodes after being amplified (making the waves bigger), and the diodes cut off the tips of those waves. The amount cut off depends on how much the signal is boosted infront of the diodes.

In a nutshell, the gain of a pedal is the input "volume" into the clipping/distortion portion of the circuit, and the volume/level is the output magnitude of the signal from that portion. There are some circuits though where the gain is a blend of the heavily distorted signal and the clean (Klon does this).

Opamps are interesting, a lot of pedals use them. It stands for operational amplifier, and I'd be lying if I told you I know how they were made and of what. A lot, maybe every time you see the option for No Diode, etc., it means Opamp only. The opamp can drive lots of volume and remain clean for a long time, vavorable for low gain and boosts, but when driven hard enough will start to clip hard. It's kind of like when you drive too much volume into headphones or speakers and they distort. There's some sweet sounds from em. In my limited experience, it provides an awesome roar. Looking glass from DOD/Shoe is a great example, and I believe a ton of the distortion from the 70s used Opamps.

I'll step down from the soapbox now.

Alright, I did some quick research:
There are at least 2 "308" chips (LM308 and UA308). It seems early versions of the Iron Pig use the LM308, since the current page lists that as of May 2019, the UA308 chip will be used. General consensus is that they sound pretty much identical. Also, the LM308 is NOT one of the diodes (as previously mentioned!), but is an opamp. (I plead ignorance as to what those differences are, but they are apparently significant!) It seems that the Rat tone is from overdriving the LM308 opamp, and that the NC (no clipping) option on my Iron Pig omits diodes and uses the LM308 only for distortion. As noted earlier, yes, the diodes have a large effect on the tone. So far, I'm digging the LED/Sil combo of diodes, though I could certainly use most of the diode options of the Iron Pig. I've been tooling around mostly with LED/Sil, MOSFET, LED, and No Clipping and all are slightly different shades of greatness. I find the germanium and SIL diodes a little lacking in definition, though I also haven't spent much time with them. They're probably fine when tweaked!

Thanks all for keeping me informed! Never hurts to learn something about your gear.

My HM-2 is now off the main board, so I went and messed with my Throat Locust (HM-2) on the second board. Tweaked it, and got a pretty great low gain tone out of it. Gonna keep it there for now while I continue to debate the Rat options.

I need to get off my butt and just get an HM-2 of some sort.
 
It's great. I don't have a Model T to A/B them, but it sounded really good. The only reason it's not still on my board is because I replaced it with a Tube Beta hybrid from Correct Sound.

Nice, I'll have to check out both more, thanks!

Thanks man, I really appreciate that. Frickin love this forum. I'll keep y'all updated if I find any of it.

I'll find a way to chip in. I can spare some patch cables. Hell, I got some spare stuff to build a pedalboard for you. What size was yours, did you want bigger/smaller?

@Novarocker Thanks for dropping the (literal) science on us.

Oh hell I didn't know this group existed. Too many pages to catch up completely.

I have recently started a doom project with a friend. We are calling it Utumno, because we are both colossal Tolkien nerds.

We're aiming for a very slow, down tuned (drop A#), atmospheric death doom thing.

I will post a song sample soon.
Fellow Tolkien nerd here. Really looking forward to hearing this!
 
Hey guys just wanted to say thanks for the gear and the kind thoughts. I've had so many people that have offered help in various ways and it's really helped with my playing situation as well as with my faith in humanity. I'm hopeful I'll be reunited with my bass again one day as it is very unique but I'm afraid the board may be long gone...

Nice, I'll have to check out both more, thanks!

My board was small. let me check how many spare patch cables I have when I get home but I may have enough as is. I'd appreciate anything though! Was planning on going with a plywood board for the time being! Thank you!
 
Even further thoughts: The Cat Tail seems more tempting to me in the limited bass demos I've seen. Anybody use one of those? Thoughts on the 2nd distortion mod? It seems like there would be volume jumps if there are significantly different levels of distortion between settings 1 and 2. If that's the case, stock seems to be the option for me, or maybe with a clean blend.

Have one and really dig it. Mine is stock, so I can't comment on the second distortion mod. I'd reach out to the company, they are pretty responsive.

Welcome to Hell. We have cookies. And fuzz pedals.

I ended up with two Arion Metal Masters for some reason, let me send you one.

I had no clue that the Metal Master was a HM-2 clone of sorts?!?

I bought one a while back because I read that the Mayhem guitar tone was created with a Tube Screamer into a Metal Master which might be BS after looking into it all some more this evening.

I'll have to bust out the Metal Master and see how it sounds on bass. I used to use the HM-2 for my Death and Hardcore projects/bands.

I love the Metal Master on bass! It seems to have more oomph in the low mids, making it really punch. I think the same thing is why I don't like it on guitar as much - it's not as grindy as other HM-2s and seems a little looser. But it is by far my favorite "budget" HM-2 for bass. Considering I got mine for $40, and the others I prefer for bass were both $160 (Throat Locust and Dunwich DIY), I can't complain. My favorite HM-2 is either the Throat Locust (for versatility) or Dunwich DIY (for more "traditional" HM-2 insanity).

This doesn't look like it would be comfortable...

Lol-Cats will get on/into just about anything…

One of ours broke a vase today that my Wife has had for years…To add insult to injury it was on the kitchen counter where they know they aren’t supposed to be…

Ashamed to admit this, but when I initially heard it break when I was upstairs my initial panic was that they had broken an expensive and VERY beloved Water pipe…Um…For “tobacco”…

Was relieved they didn’t break my beloved Death Metal beaker glass…

Could totally see one of our cats getting up on top of a rig like that…

Probably a good thing to keep in mind when I finally assemble the rig I want…

Thanks! \m/

Would love to hear ya’ll based on your genre description…

Someone on this thread recommended this album to me a few weeks back…LOVING this album so far (which sorta fits your description of atmospheric Death Metal):



Thanks! \m/
